Title: Electrohydraulic transducer apparatus
IPC: B21D26/12
Filed: 1969-09-10
Abstract: 1,271,723. Electrohydraulic forming; making cans. CONTINENTAL CAN CO., Inc. 10 Sept., 1969 [25 Sept., 1968 (2)], No. 44697/69. Headings B3A and B3Q.  Apparatus for forming a workpiece T, Fig. 1, e.g. a can or a plastic or paper container, between the flexible wall 23 of a chamber and surrounding die 40, 41 comprises a pair of electrodes 33, 34 within the chamber, a cage 11 supporting the flexible wall and having spaced members 12, 13 at opposite ends of the chamber, means for introducing an electrically conductive fluid into the chamber and for increasing its pressure so as to rough-form the workpiece, and a source of electrical potential for producing a discharge in the fluid between the electrodes to further form the workpiece. The gap 37 between the heads 35, 36 of the screwthreaded electrodes may be adjusted by rotating the electrodes. Coaxially-spaced electrodes may be used, Fig. 3 (not shown), and a piston 121, Fig. 5, for clamping the edge of the workpiece against the die by means of the conductive fluid, which may be a saline solution. After forming the workpiece, the fluid is withdrawn, creating a partial vacuum to lift the piston 121. The apparatus may be embodied in a can styling machine having a rotatable turret 212, Fig. 10, carrying four split dies 213, Fig. 16, electro-hydraulic forming heads and elevatable supports 215 for cans. A can is fed to the support 215 at the receiving station by a wheel 216 and held by vacuum as the support is raised to place the can over the flexible wall of an electrohydraulic forming head 214, Fig. 15. After the support is raised the die-halves 218, 220 close from a part-closed to a completely closed position, and the vacuum is interrupted. Springs 314, Fig. 20, acting on the head of the support, press the can against the forming head before the die is closed. Liquid is then introduced for inflating the can, followed by a spark discharge before the can is discharged by a wheel 223. The turret is turned by a gear 227 so that the supports 215 are elevated by a cam track 302 which operates slides 297 carrying the supports. Above the turret is a stationary cam 383 for operating the die-halves by means of slides 378 and links 362, 370, 375, Fig. 25, on the turret. A post 408, Fig. 33, pivotally-supports contacts 395, 396, through which a pulse of electrical energy may be transmitted to forming head contacts 385, 386 when these are appropriately positioned by rotation of the turret. After the styling operation, the dies are completely opened, the vacuum re-imposed in the holder which is lowered and the can is removed by a wheel 223, Fig. 10. An hydraulic control circuit, Fig. 13 (not shown), includes an isolator (435) between the supply of saline solution to the forming heads and the hydraulic fluid pressurizing the solution. In another construction, the holder may be raised by a fluid motor.

Title: Method of and an apparatus for inspecting a travelling sheet material to detect defects
IPC: G01N21/892
Filed: 1974-11-05
Abstract: 1486612 Photo-electric detection of flaws KAWASAKI STEEL CORP and TOEI DENSHI KOGYO KK 5 Nov 1974 [13 Nov 1973] 47844/74 Heading G1A To analyze defects in a travelling strip 1, Fig. 1, it is scanned with light from a source 2, and light reflected (or transmitted) by the strip is received by detector 5; the detector signal is then pro-  cessed to find the width, quantity, length and depth of the defects in the scan, and each of these factors is quantified to show whether it is small, medium or large. The factors are then combined to give an indication of the usability of the strip. The detector signal is amplified at 6 and differentiated at 7; the parts of the signal due to the edges of the strip are blanked out. The width is measured at A, the quantity at B, the length at C and the depth at D. These factors are stored in memories M1-M9 and gated together at AND 1- AND 27 for printing to indicate usability. Width: the detector output for dark and bright defects is shown in Fig. 3, and the differentiated  signal from 7 is shown at (a). This latter produces a pulse from bi-stable 11a or 11b depending on the initial polarity of the signal from the detector; the bi-stable's output lasts whilst the defect is being scanned, and is used to gate pulses from an oscillator 13 in timing section E to a counter 15. The counter output is thus a measure of the defect width, and is quantified into small, medium or large at pre-set outputs 16, 17 and 18. Quantity: the signal from 7 activates a differential amplifier 19 in section B whenever the signal exceeds a reference voltage 20. The number of times this happens in a scan is counted at 21 and quantified into small, medium or large on lines N1, N2 or N3.  Length: whenever the signal from 7 exceeds reference voltages 23 or 25 in section D, their associated differential amplifiers activate OR gate 26 in section C. This in turn activates bi-stable 27 and counter 28; these also receive a pulse every 5mm. of travel of the sheet, so that the number of 5mm. lengths of travel which contain a defect are counted at 28. This count is quantified at 29, 30, 31.  Depth: by comparing the signal from 7 with reference voltages 23, 25 in section D it is possible to determine whether the signal lies below both references, between them, or above both, thus quantifying the depth. Combination: The first three factors above are stored at M1-M9 and combined at AND 1-AND 27 with a timing signal derived from OR gate 26 via inverter 32 and capacitor 33; these AND gates operate a printer (not shown) which indicates which of 27 categories the sheet is in. The timing signal also resets the stores via delay 34. The 27 categories are formed into two groups indicating how usable the sheet is, and are connected to OR gates 41, 42; these gates are connected to AND gates 43-46 which also receive depth signals from section D and produce a further three outputs for operating a sorter to sort tested sheets into piles of good, less good and unusable.
